Ultimate tensile strength of tooth structures
Dental Materials, 2004This study determined the ultimate tensile strength (UTS) of enamel (E), dentin (D) and dentin-enamel junction (DEJ) using the microtensile technique. It was hypothesized that the UTS of dental structures varies according to location and nature.Intact occlusal enamel surfaces from extracted human third molars were etched with 37% phosphoric acid and ...

Ultimate Bending Strength of Si Nanowires
Nano Letters, 2012Test platforms for the ideal strength of materials are provided by almost defect-free nanostructures (nanowires, nanotubes, nanoparticles, for example). In this work, the ultimate bending strengths of Si nanowires with radii in the 20-60 nm range were investigated by using a new bending protocol.

The ultimate strength of suture anchors
Arthroscopy: The Journal of Arthroscopic & Related Surgery, 1995Suture anchors of various designs are gaining acceptance for open and arthroscopic procedures. The rapid proliferation of these devices challenges those using them to apply objective criteria for device selection. Comparative data on implant security in different settings, modes of failure, and ultimate failure strengths is lacking.

High-Strength Concrete in Ultimate Strength Design
Journal of the Structural Division, 1978The ultimate behavior of concrete structural members was predicted based on the knowledge of the concrete and the steel stress-strain curves and using nonlinear computerized methods. The calculated values of ultimate moment and curvature were compared with some experimental values for beams and columns.

ACI Journal Proceedings, 1965
THE BEHAVIOR OF CONCRETE SECTIONS AT FAILURE IS CONSIDERED AND THE VALIDITY OF ULTIMATE STRENGTH DESIGN METHODS DEMONSTRATED. THE DIFFICULTIES EXPERIENCED BY DESIGN ENGINEERS IN APPLYING EXISTING CODE FORMULAS ARE SUMMARIZED. AN UNDERSTANDING OF THE BASIC PRINCIPLES OF ULTIMATE STRENGTH METHODS LEADS TO RAPID AND DIRECT DESIGN.

ULTIMATE STRENGTH OF COMPOSITE BEAMS.
Proceedings of the Institution of Civil Engineers, 1965SIMPLE METHODS OF PREDICTING THE ULTIMATE MOMENT OF RESISTANCE AND THE CURVATURE OF CROSS-SECTIONS OF COMPOSITE STEEL-CONCRETE BEAMS ARE PRESENTED, BASED ON RECENT RESEARCH ON THE STRESS/STRAIN CURVE FOR CONCRETE. THESE DESIGN METHODS ARE COMPARED WITH THE RESULTS OF LABORATORY TESTS AND WITH SIMULATED TESTS CARRIED OUT ON A COMPUTER. /RRL/A/

Ultimate Strength of Tubular Joints
Offshore Technology Conference, 1976ABSTRACT Tubular joint ultimate strength equations that are helpful for offshore platform design are presented. The formulae are based on data from 346 joint tests. They are easy to use and cover more joint configurations than present design procedures.

The ultimate strength of solids
Canadian Metallurgical Quarterly, 1974AbstractThere is an upper limit to the mechanical strength of any material under any particular test conditions. This limit is known as the ideal strength. The present paper attempts to define the ideal strength as closely as is presently possible. To this end, a brief account is first given of some of the highest strengths recorded experimentally ...

Ultimate Strength of Aircraft Structures
Volume 1: Advances in Aerospace Technology, 2014Strength analysis of aircraft structures focuses on static strength, fatigue, and damage tolerance of the materials. Countless hours are invested in quantifying the static strength, which is allowed to fully yield under ultimate loads so that the structure can be designed as light and efficient as possible.
